Well never towed a car,but I had a rail on my z1 sidecar rig and halled many bikes in on thursday nights that the popo got them for DUI and speeding not to mention pulling my fishing boat 10' , Drag bike and a cooker behind the rig. Cars where way to big back then I learned the rail trick from my dad. Dam he gets smarter all the time :)hehe pop was way ahead of his time _________________"So Soon Old & So Late Smart"
